Title: Innovations of Sheetal Kumar Jain
Introduction
Sheetal Kumar Jain is a notable inventor based in Andhra, India. She has made significant contributions to the field of digital technology, particularly in the area of radio frequency modulation. Her innovative work has led to the development of a unique digital radio frequency (RF) modulator.
Latest Patents
Sheetal holds a patent for her invention titled "Digital Radio Frequency (RF) Modulator." This RF modulator provides modulation for base-band TV signals. It enables direct conversion of digital base-band audio and video signals to a desired RF channel frequency, eliminating the need for analog up conversion. The RF modulator comprises an audio module, a video module, and an RF converter. The audio module features a pre-emphasis filter, a multi-stage audio interpolator, and a complex frequency modulator to generate frequency modulated (FM) audio signals. The video module includes a complex VSB filter, a group-delay compensation filter, and processing logic to produce a filtered output video signal. The RF converter consists of a complex adder, a complex multiplier, and an RF interpolator to construct the base band TV signals and shift them in the frequency domain to the desired RF channel frequency. The exponential video carrier is generated at baseband, with a frequency value in the range of ±13.5 MHz. The RF interpolator includes zero pad logic followed by a quadrature band pass filter (BPF), with an optional second stage of another zero-pad logic followed by a real band pass filter (BPF) if the desired RF channel is in the higher VHF band.
